Though Robert Casadesus (1899–1972) had the most visible career as a performing and recording artist, his wife and son were also fine musicians who frequently concertized independently. The film moves between the family's idyllic country haven and various concert venues and is augmented by selections from the Bell Telephone Hour. Robert is heard in movements from sonatas of Beethoven and Chopin; Jean performs solo music of Debussy and a movement of the Saint-Saëns Piano Concerto No. 2; and all three join together in movements of concerti for three keyboards by Bach, BWV 1063 and 1064. Other works sampled include Beethoven's Piano Sonata No. 23 ("Appassionata") and Debussy's "Feux d'artifice."

"It's pleasant to see the 'first family' in their home surroundings and Robert does nice take-offs of the pianist flamboyant and the pianist intense (à la Glenn Gould)…. It's from Robert that we get the marvellous contrasts of light and shade and a more winning and seductive tone…. The shaping of the last movement of the Chopin B minor Sonata is masterly, with just enough rubato to tell us where we are in the structure and plenty of inner flamboyance."—Gramophone
